10pk Control Arm Shims .185in Dual Mount

The 10pk Control Arm Shims .185in Dual Mount from ALLSTAR PERFORMANCE is an essential alignment correction tool for serious chassis builders, drag racers, and suspension-tuning enthusiasts. Control arm shims are critical fasteners that allow you to adjust the geometric relationship between the control arm and frame, correcting camber and caster angles with precision. This 10-pack provides multiple shims for a single vehicle or stocking spares for your shop, making it ideal for competitive motorsports, street rod builds, and high-performance street applications where suspension geometry directly impacts handling, tire wear, and cornering performance.

Each shim measures .185 inches thick and features a dual-mount design, allowing installation at both upper and lower control arm attachment points. The .185-inch thickness is a standard increment in suspension work, enabling fine-tuned geometry adjustments that compound across multiple shim applications. Manufactured by ALLSTAR PERFORMANCE—a trusted name in dirt track and drag racing components—these shims are precision-cut and engineered to withstand the extreme loads and vibration cycles of high-performance driving. The dual-mount configuration simplifies installation by reducing the number of separate parts required and ensuring consistent geometry correction without the need for custom machining or frame modification.

This product is ideal for fabricators, race teams, and mechanics working on independent front suspension systems where bolt-on alignment correction is required. Common applications include circle-track racing (dirt and asphalt), drag racing launches, vintage hot rod restorations, and street performance vehicles. The 10-pack quantity is sufficient for a complete front-end alignment job with spares for future adjustments or additional projects. Installation is straightforward: simply insert shims between the control arm and mounting bracket, then re-torque fasteners to OEM specifications. Always verify your vehicle's suspension geometry with a four-wheel alignment tool after shim installation to confirm that camber, caster, and toe angles meet your setup requirements.
